4 Claims.

This invention relates in general to stoves, and has more particularreference to stove top covers of simple construction, which may beraised and lowered into and out ofposition with ease of operation. Thisapplication is a division of my application Serial No. 665,941, filedApril 13, 1933. An important object of the invention isthe provision ofa stove top cover which is insulated against heat when the table top islowered after the burners have been used. g

A further important object of the invention is the provision of a stovetop cover which may easily be raised or lowered without requiring themoving or. adjusting of other parts.

Another important object of the invention is Figure 1 is a frontelevation of a stove embody- ,ing my present invention;

Fig. 2 is a transverse vertical section through the top of the burnerbox unit of a stove embodying my invention;

Fig. 3 is a rear elevation of the burner with the top in closedposition;

Fig. 4 is a fragmentary rear elevation with the 35 top shown in raisedposition;

Fig. 5 is a section taken substantially on the line 5-5 of Fig. 3; and

Fig. 6 is a section similar to Fig. 5 and showing 40 the top in raisedposition.

For the purpose of illustrating my invention I have shown on thedrawings a stove construction generally, comprising a frame IS, acombined oven and broiler unit l6, and a burner box unit l1. Four legsl8, of suitable form and: construc- 45 tion, are provided at their topswith flat parts arranged at right angles and adapted to receive fourangle iron rails which may be bolted in place. These angle iron railsare arranged so that the apex or corners of the angles are adjacent and50 with an opening through the stove.

As more particularly describedin my co-pending application, of whichthis is a division, the combined oven and broiler unit I6 and burner boxunit I! are so constructed'that they fit within,

the bottom frame thus provided and restupon the tops of the side and endrails. The burner box unit, to which the instant invention moreparticularly relates, is a completely enclosed integral unit andcontains a drawer l9 mounted below a burner containing section,indicated at 2 I. 5

As will lie-apparent from the drawings, the burner box unit comprises anintegral unit and consists of a bottom plate .of pressed sheet metal,side walls, a back wall 22, a top rectangular frame 23 of angle ironconstruction, and a front cast 10 rectangular frame 24. These parts areso constructed and arranged as to greatly facilitate assembly and toproduce a rigid, substantial structure of relatively light gaugematerial.

The top frame consists of four angle irons 15 welded together at theirends, the two side angle irons extending across'the ends of the frontand back angle irons. The horizontal flanges of all four angle irons areat the top, and those of the side angle irons extend outwardly and thoseof the front and back angle irons extend forwardly.

Viewing Fig. 2, the front cast frame 24 is provided with an inset topflange 25 at the opening. Bolts 26 are arranged to extend rearwardlyfrom the top of the frame '24 through openingsin 25 the front angle ironof the top frame.

The back wall 22 consists of a single flat sheet of metal secured at 21to the rear face of the rear angle member of the top frame and to theinner face of the rear upturned flange of the bottom plate.

As shown in Fig. 2, the burner box unit is provided with a cast ironstove top 28 and a a skeleton vessel supporting grate 29 of usual orpreferred construction. A front wall of the burner compartment 3| isprovided to fit within and suitably secured to the top part of the frontcast iron frame 24 of the stove. A manifold 32 for the burners isarranged within this unit and back of the wall 3|. It enters the unitthrough an opening at the rear and is'disposed along one side wall andacross the front of the unit. It is held 'in position from the frontcast frame and to this ,end clamping membersor arms 33 are cast integralwith the frame and cooperate with companion clamping members 34 to holdthe manifold in position. Burner valves 35 are arranged to extend upfrom the manifold and have gas outlets 36 adapted to be arranged in themixing chambers 31 of burners 38. These burners are supported at thefront upon the gas outlets 36 and at the rear upon brackets 39 of angleform which extend down from a fastening means 4|.fro'm the top angleiron 23 along the front of the back wall and thence forwardly be A fixedsheet metal apron 44 extends up from andis spaced above the top plane ofthe burner box unit I! and is rigidly secured thereto. This apronextends longitudinally of the burner box unit or stove and'is' providedat its ends with flanges 45 extending'rearwardly to allow ofits beingrigidly secured by vertical brackets or posts 45 spaced slightly awayfrom the side edges of the apron, as shown in Figs. 3 and 4. These posts45 are secured at their lower ends to the burner box 1 3 indicated at 41by bolts .48 or other suitable fastening means. Adjacent the top andbottom of its flanged edges, the apron is secured to the verticalsupporting posts at 49 by bolts or other suitable fastening means. Asshown in Figs. 5 and 6,-the apron with its supporting brackets or postsis spaced rearwardly from the vertical plane of the back wall 22 of theburner box unit, for a purpose which will later be described. v A tabletop stove cover, generally indicated at 5|, is provided for the burnerbox unit and is or may be providedwith a handle 52 to facilitate raisingand lowering. This top is hinged at 53 along the rear of the stove andpreferably consists of two metal sheets, the topmost one of which isflanged downwardly at 54 at the front of the stove, and thence inwardlyat 55 to provide a box-like edge. The inwardly extending portion 55rests upon a projection 55 of any suitable material secured either tothe stove top or to the cover.

The top plate of the table top extends rearwardly through an opening orslot 51 provided between the top of the back wall 22, extension 58,

and the lower edge of apron 44. This extension 58, extendinglongitudinally of the rear wall of the stove, is secured to the back 22at 21 and forms a part of the hinge 53. The rearward extension of theplate 5| is bent upwardly and thence rearwardly at 53 to receive an arm5| to which one end of a counterbalancing spring 52 is connected. Theother end 52 of the spring is fastened to the back of the stove at 53 asmay be observed in Fig. 3 and two such springs are provided.

The lower sheet of the table top of the stove, indicated by referencecharacter 54, is flanged at its front end, then extended forwardly untilit contacts the inwardly extending portion 55 of the top sheet of thetable top where it is bent so as to overlie .and rest upon the inwardlyextending portion 55 where it is spot welded or otherwise suitablysecured. At its rear end it is flanged downwardly at 55, then rearwardlyand upwardly, as indicated at 55, and against the back extension 58.This construction creates a box-like structure 51 which provides an airspace within the table top to insulate its upper surface from the heatof the burners when the top is lowered after the burners have been inservice. If desired, this space may be filled with insulating materialof any desired character.

It will be apparent from the foregoing description that the table top orcover may be readily raised or lowered without aflecting the relativeposition of the other parts of the stove. When the top 5! is raised thatportion of the top plate which extends rearwardly of back wall extension58 rests against this extension and the cover portion itself restsagainst the apron 44. as shown in Fig. 6.

It will be manifest that when the table top is raised thecounterbalancing spring will serve to securely support and maintain itin upright position, and that because of the novel construction of theparts, very little efiort is needed to lower the top to closed position.When the top is closed down over the burners its weight will besufficient to overcome the tension of the counterbalancing spring.

It is thought that the invention and many of its attendant advantageswill beunderstood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.
